Stimulus

Historian: In rebuttal of my claim that West influenced Stuart, some people point out that West's work is mentioned only once in Stuart's diaries. But Stuart's diaries mention several meetings with West, and Stuart's close friend, Abella, studied under West. Furthermore, though now commonplace, none of Stuart's contemporaries used.

Answer choices

  1. Out Of Scope: “discussions with Abella”15% picked this

    Stuart's discussions with Abella were one of the means by which

    Tempting. It never said that Stuart had any discussions with Abella about West, just that Stuart and Abella were good friends and that Abella studied under West. It definitely seems like the author brought up Stuart’s friendship with Abella in service of her larger point that West influenced Stuart. But the author may have just been showing a way that Stuart would be aware of West. If my friend is taking a class from a certain professor, that may inspire me to look up that professor’s work, even if I never discuss that work with my friend. Ultimately, I would be okay picking this answer if D weren’t there.

  2. Unsupported Comparison4% picked this

    It is more likely that Stuart influenced West than that West

    The author is certainly not drifting towards this conclusion. She’s trying to support her original idea that West influenced Stuart.

  3. Too Strong: "not influenced"5% picked this

    Stuart's contemporaries were not influenced by

    We can’t support a strong idea about all of Stuart’s contemporaries. All we know about them is that they did not use West’s terminology. But it’s a big stretch to go from “didn’t use West’s terminology” to “were not at all influenced by West”.

  4. Correct75% picked this

    Stuart's work was not entirely free from

    Why this is right

    This is just a very safe way of reiterating the Historian’s original claim. We can support this pretty directly by pointing to the last sentence. If Stuart was using West’s terminology (at a time when it wasn’t otherwise used), then it looks like Stuart was at least partially influenced by West.

    Skill tested: Most Supported · how this choice captures the argument's function is the move to repeat next time.

  5. Out Of Scope1% picked this

    Because of Stuart's influence on other people, West's terminology is

    Out Of Scope: “Stuart’s influence on other people” We never hear anything about Stuart influencing other people, so we would be totally speculating to think that Stuart ended up popularizing West’s terminology.
